  1. If the amplitude is 0.5, and the magnitude of the quake is 4.3, what is the time difference between the P and S waves?
  2. If the earthquake is 100 miles from the seismic station, and the amplitude is 1 mm, what is the magnitude of the quake?
  3. If the amplitude is 100 mm, and the magnitude of the quake is 6.0. how far away from the seismic station was the quake?

 

  1. Below is an image from Anchorage, Alaska, after the 1964 earthquake. What was the magnitude of this quake?
  2. From this same picture, how would you rate this quake on the Mercalli scale and why?
